This invention. p relates to.fi1up rovements in hydrocarbon burners. V

iThe object of the.pkresentdnvention .is to improve the construction Yof hydrocarbon burners andI to provide a: simple, practical and inexpensive hydrocarbon burner `of strong and durable construction which will be adapted for burning kerosene and to crack orbreak upfthe lkerosene Yinto a gas.

Au `further object off? the invention is to provide a hydrocarbon:burner of this charactor equipped with .a cracking Vchamber adapted to he heated .by hea radiated from the combustion.chamberyan maintained at ai temperatureadapted to produce atlemc Y which xvill. *remainV Y approiizimately'l at.. the same height, after 4the burner yhas been oper.- ated for a .considerable perio when first started Sothat the rcontinued operation ofjhe burner will not produce too excessive .heat inthe presence of the kerosene passing through the crackingchamber.

,Y the `scope of the claiinsLmay be resorted to without departing from `the spirit o r sacri` fieing any ofthe adventages of the inven- =tion. C Inthe drawing:

4igure l 1s a vertical Sectional view of a lhydrocarbon burner constructed in accordance `with this invention.

Fig. 2 is a plan view of the detlecting plate.

Like numerals of reference designate coril lu'strated the preferred embodiment of the invention, the hydrocarbon burner comprises in. its construction an annular horizontally disposed member l preferably eon sisting of a casting and provided with a central opening 2 and having au interior annular chamber 3 surrounding the central parts in allthe figures of the Y opening and adapted to forni a cracking l chamber. The annular nienibeizavliicli is supported by a eubstantially cylindrical shell or easing 4, is provided with aninflet opening 5 threaded to ieeeive the threaded .end 6 of a nipple/", which is adapted :to be connected with any suitable source ofsupply. The casing or shell 4., which receives within its upper portion the annular mem` bei' l, is secured to the `same by means of screws 8. or other suitable fastening devices, and it is of cylindrical .form to conform ltothe configuration of lthe aniuilaiI memel' l. r A t Y `The `annular member 1 is provided at its .upper face with a recess or eoncavity 9,v and the upper edges of the annular member 1 `fit in a lower peripheral recess 10 of a top plate 11 forming a deflecting plate for the hydrocarbon burner and removably iitted onthe said annular member 1. The top or plate 11 extends above the shell or casing 4, and the annular recess forms a shoulder or seat to rest up'onthe upper edges of the annular member and at the same time p21-ovides a reduced portion to eXtend'iiitothe coneavity or recess 9 so as to interlock the top or plate 1l with the annular member and thereby prevent accidental displacementoffthehfprmer. The deiiecting plate by an adjustment ot' the needle valve.

1l is spaced Afrom the bottom of the recess or concavily 9 of the annular member 1 to provide a combustion chamber and the top or plate 11 is provided with an imperforate central portion and it has upwardly tapered openings 1:2 surrounding the solid or imperf'oratc central portion and located at the outer portion of the combustion chamber beyond the central opening the imperferate area or solid portion of the top or plate 11 being greater than the opening Q and extending beyond the same so that the gas from the burner will be projected through the opening Z against the imperforate portion of the defiecting plate 11. producing a thorough mixing oi? the and air and providing a mixture which is adapted to burn with a blue flame which, owing to the curvature of the bottom ot' the recess or eoncavity 9. finds an easy passage to the outlet openings 12, and a blue flame is produced which burns from the central opening 2 to the outlet openings. This tends to keep the combustion chamber free from soot and accumulation. The cracking chamber 3. which receives the kerosene and breaks the same up into a gas, is heated by the heat radiated from the combustion chamber and the gas passes downward through an approximately L-shaped pipe 123 having an upwardly extending vertical arm and an inwardly extending horizontal arm, the vertical arm being threaded at 14 into the bottom of the cracking chamber and the hori zontal arm being provided with a threaded terminal 15 which is connected with a needle valve easing 1G having a threaded opening at one side to receive the horizontal arm of the pi )e 13. The needle valve casing. which pre erably consists of a casting, is equipped with a packing nut 17. and the valve proper 18 consists ot" a rod re duced at the upper portion to form a shoulder 19 and to provide a pin or extension Q0. The extension or needle 2O passes through a jet opening 21 ofthe needle valve easing and is adapted to maintain the same in a clean condition by removing the foreign matter, such as amorphous wax. etc..` from the said opening. This removal of the wax and cleaning of the jet opening is effected No claim is made in the present application to such construction. as it forms the subjectmatter of an application filed by me March 1t). 1917. Serial No. 153,893. Patent No. 1.241.331. Sept. E25. 1917. The needle valve is connected b v a suitable pivot` 22 with an operating lever fulcrumed at its rear end at .24 and having its f'ront portion extending through a slot 25 of the shell or easing and adapted to be readily grasped by the operator to adjust the needle valve.

The kerosene entering the cracking chamber breaks up into gas and passes out from the cracking chamber through the pipe 1? to the needle valve and it escapes through the needle valve casing at the jet opening in the form of a which impinges against the under side of' the defleeting plate 11.

breaking and extendingI and spreading outward inte the combustion chamber and passing out through the outlet openings 12. The upward curve of the marginal portion o1 the recess or conravity t) allows an easy passage of the flame from the combustion chamber to the openings 12, The size of the annular member not only increases the life and durability of the same by preventing the annular member from burning out but it also insures a longer passage of the gases from the inlet opening 2 of the combustion chamber to the outlet oienings 12. The flame in passing out of the burner will remain at the same or approximately the same height any number of hours after the generation of gas in the collecting chamber and it does not vary after the burner has been in operation for some time. as there is no liability1 of the cracking chamber becoming excessively heated owing to the placing of' the combustion chamber over the cracking chamber. This has been found by experience and the device is also rendered easily and cheaply nianufactured owing to the simplification of the construction. Y

The hydrocarbon burner is preferably equipped with a supplemental or auxiliary cap '26 supported above in spaced relation with the defleeting plate 11 by a depending annular flange Q7 which fits in a peripheral recess :28 of the defiecting plate. The super imposed cap is provided with holes 29, and the purpose of the cap is to allow the escaping flame to reach a higher elevation and have a more uniform blue color.

What is claimed is:

1. A hydrocarbon burner including an outer easing. a gas generatingmember removably secured to same. said gas generating member having a central opening therethrough and an. interior chamber surrounding the same. said gas generating member having a concave recess in its upper surface. said chamber being provided with inlet and outlet openings. a detieeting plate supported by and above the gas geul erating member, said deflecting plate having a peripheral recess in its upper surface` and a cap supported in spaced relation to the deflecting plate.
